Species Censes & Local Conceptions Of Ornithological Fauna, Uzi, Alexandria Vandervest
Independent Study Project (ISP) Collection
Uzi Island is a rapidly growing and developing island with a wealth of flora and fauna found in very few other places around the world. Study is needed in every field, this was a preliminary study into the residential and migrant bird species presence on Uzi Island. Birds were observed in two of the main habitats present on Uzi Island, intertidal/mangrove and coral-rag. Three transects were cut and laid through each of the two habitats and monitored in the morning and evening hours over the course of 20 days. A total of 1949 birds were recorded comprising 71 species (708 …
Pollinator Habitat Availability And Diversity In Various Tropical Agroforestry Management Systems Of Coffea Arabica In Santa Clara, Chiriqui, Julia Brokaw
Independent Study Project (ISP) Collection
Habitat loss due to increasing agricultural intensification and chemical use may result in the loss of biodiversity of bee species. This has implications for global economies and food security for people world wide. Focusing on coffee cultivation, an important cash crop in the tropics, this study aims to understand the availability for pollinator habitat resources in a management gradient from shade-grown coffee agroforestry to conventional farming systems that employ both organic and non-organic management practices. I examined the influence of farming and land-use practices on the availability and quality of habitats for social and solitary bee species through observations of …
Comparison Study Of Fish Species Richness Of Two Mangrove Forests On Misali Island: Eastern (Extractive) V. Western (Core) Mangrove Forests, Spencer M. Mallette
Comparison Study Of Fish Species Richness Of Two Mangrove Forests On Misali Island: Eastern (Extractive) V. Western (Core) Mangrove Forests, Spencer M. Mallette
Independent Study Project (ISP) Collection
The fish species richness of two mangrove forests adjacent to non-extractive and extractive zones, respectively, was investigated on Misali Island, Tanzania. Observations were done at each site for seven samplings, recording the different species observed upon each visit. A general list of species found in the intertidal area was also composed to get an idea of what species use this region as well. A total of twenty-four species were observed between the two sites, leading to a similarity index of 0.29, representing very little similarity between the two stands. Two different diversity indices (Shannon-Wiener and Simpson’s) also supported the hypothesis …
Marine Turtle Health Assessment And Aquarium Suitability: Uzi Island, Zanzibar, Olivia “Warda” Crane
Marine Turtle Health Assessment And Aquarium Suitability: Uzi Island, Zanzibar, Olivia “Warda” Crane
Independent Study Project (ISP) Collection
This study assessed the health of the marine turtles in the aquarium on Uzi Island. Health evaluations of each turtle included size, eating habit, and physical abnormalities. Behaviorally the sea turtles were observed at two different time periods multiple times. Results were compared to research on wild sea turtles. The conditions of the aquarium were evaluated for water quality and holding capacity. The water temperature, pH, and salinity levels were tested to assess the water quality. The results showed that the overall health of the sea turtles were positive from the normal activities and few abnormalities. The overall aquarium conditions …
An Integrated Research Approach To The Development Of Fungal Isolates As Bioherbicides For The Control Of Woody Weeds, Patrick Mershon
An Integrated Research Approach To The Development Of Fungal Isolates As Bioherbicides For The Control Of Woody Weeds, Patrick Mershon
Independent Study Project (ISP) Collection
Prickly acacia (Acacia nilotica) is an invasive weed tree in Australia, ranked seventh on the list of Weeds of National Significance because of its aggressiveness and its economic and environmental impacts. The significant downsides to manual and chemical control of this species drove the search for a biological control mechanism. Surveying and sampling stands of A. nilotica naturally exhibiting disease symptoms yielded several native Australian fungi capable of pathogenesis in this species, which are currently under assessment as potential bioherbicides for this weed. Three field trials were established at the same site in order to further advance current …
A Woolly Monkey Travel Guide: An Assessment Of The Foraging Patterns Among Lagothrix Poeppigii On Sumak Allpa Island, Ecuador, Adrienne Mathis
A Woolly Monkey Travel Guide: An Assessment Of The Foraging Patterns Among Lagothrix Poeppigii On Sumak Allpa Island, Ecuador, Adrienne Mathis
Independent Study Project (ISP) Collection
This project was conducted to assess the foraging patterns of a troupe of seven woolly monkeys, Lagothrix poeppigii, on Sumak Allpa island in the eastern part of the Ecuadorian Amazon. Recently, many studies concerning woolly monkey foraging and nutrition have been conducted near this area in Yasuní National Park, and these studies have defined this species of monkey as generalized frugivores (Stevenson, 2004). During this study, we observed the monkeys during 22 separate foraging sessions and recorded which plant families and species the troupe foraged from during these sessions. We then mapped the locations of the species which the …
Implications For Soil Microbe Research: Investigations Into The Feasibility Of Dna Amplification From Stained Roots And Temporal Patterns In Arbuscular Mycorrhizal Fungal Communities., Catherine Ausland
Independent Study Project (ISP) Collection
Arbuscular mycorrhizal (AM) fungi are obligate biotrophs that form symbiotic relationships with 80% of vascular plants around the world. Because of their beneficial relationship with plants in almost all terrestrial ecosystems, the implication of utilizing AM fungi in ecological restorations is immense. The following investigations seek to increase knowledge of the community ecology of AM fungi in order to enhance the potential for use of AM in ecological restoration. The first investigation replicated a novel method of AM visualization in plant roots, utilizing ink and vinegar as less destructive staining agents, to determine whether molecular studies could be feasibly performed …
